Question 8 (5 points) Find the zero of 5x - 20 = 0.
O a) 4
Ob) -20
3
Oc) 0
O d) 5

x=4

Step-by-step explanation:

5x - 20 = 0

Add 20 to each side

5x = 20

Divide by 5

5x/5 = 20/5

x =4

The zero is when x = 4

a) 4

Step-by-step explanation:

To find the zero of 5x - 20 = 0, find the value of x.

5x - 20 = 0

Add 20 to both sides.

5x - 20 + 20 = 0 + 20

5x = 20

Divide both sides by 5.

(5x)/5 = 20/5

x = 4

The zero of 5x - 20 = 0 is 4.
